Enhanced security in cloud applications using emerging blockchain security algorithm

摘要

Cloud computing is one of the biggest distributed platforms accomplishing with parallel processing. Cloud computing is a household buzzword. A highest portion of data transmission in entire world is using cloud. Since cloud is distributed and involved parallel processing, it is not assured that it can provide security. One of the invisible technologies changing the world is block chain (BC). Various core functions of Governments, societies, and economics using internet are highly secured due to blockchain. Blockchain is a historical record about every digital activity happen in the internet. Blockchain is a continuous collection of blocks interlinked by chains which encrypt blocks, and it cannot be modified by anyone in the world. Most of the emerging applications are suffering from intruders, anomalies, thieves and insurance companies fetching the personal information and disturbing the customer daily activities. In order to provide enhance and tighten the security level, this paper focused on designing and implementing a blockchain security for cloud applications. The entire process of the paper is simulated using JAVA and Cloud Simulator for verifying the performance. It is also evaluated by comparing the performance with the existing approaches.
